From glam to grunge: Ellie Goulding leaves TV show in pretty dress but emerges the next day in a snap-back cap and Dr Martens

Lights singer Ellie Goulding seems to be becoming accustomed to many costume changes.

The 27-year-old Between The Sheets hit maker was keen to switch up her style as she left a TV appearance on MTV looking like she was ready to hit the town in a girly cut out dress and heels.

Less than 24 hours later the blonde singer emerged dressed in a more Tomboy style than she has become associated with, leather skinny trousers, Jaded London Diamond Bomber Jacket and a printed hoody and backwards baseball cap, adding some chunky black Doc Martins for the ultimate grunge girl effect as she made her way to the Today Show.

Ellie is currently undertaking a gruelling tour, which will see her perform across the US, starting at The Theatre at Madison Square Garden in New York on Wednesday evening.

Following the US Ellie will move on to Canada before heading to Australia to play in Perth on May 28th, eventually retuning to the UK in the summer to play Wireless Festival at the beginning of July.

Although the Brit award winner showed signs she could be Burn-ing out, as she posted a picture on her Instagram page of her legs sprawled out on the floor on Wednesday with the caption: 'We've resorted to sitting on the floor. 4am start'

Tweeting just an hour before the snap Ellie indicated that she felt in need of some rest: 'What's it like not being exhausted? Just curious'

Despite feeling fatigued, her performance on The Today Show was met with praise, as she retweeted a compliment from TV host Carson Daly: 'Best #Voice out there. Hands down. Thanks for being @todayshow @elliegoulding'
